How Analyze was Used
“For quantitative measurement, visually detected DWI and MTT abnormalities were segmented in randomized order by 2 experienced neuroradiologists blinded to clinical information by using a semiautomated commercial analysis program (Analyze, Version 7.0; AnalyzeDirect, Overland Park, Kansas). Tmax maps were thresholded to 6 seconds. Absolute mismatch was defined as MTT  DWI; percentage mismatch, as (MTT  DWI) / DWI 100%.”
